GQCB022490JDT Description

The GQCB022490JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 23 resistors with a 249Ω resistance value, 5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic QSOP package, this 24-pin gull-wing SMD component offers a compact footprint (8.66mm x 6.02mm x 1.47mm) with tight tolerances (±0.1mm height, ±0.2mm depth). Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it is ideal for high-density PCB designs requiring reliable signal conditioning or voltage division.

GQCB022490JDT Features

• Thin-film technology: Delivers superior accuracy, low noise, and excellent thermal stability.
• Ceramic case: Enhances durability and heat dissipation in harsh environments.
• BUS circuit designator: Optimized for bus termination and pull-up/pull-down applications.
• QSOP package with gull-wing leads: Ensures secure surface-mount attachment and compatibility with automated assembly.
• Wide operating temperature range (-70°C to +125°C): Suitable for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Non-RoHS compliant: May be preferred for legacy or specialized systems requiring leaded components.

GQCB022490JDT Applications

This resistor network excels in:

• Signal conditioning in data acquisition systems and ADC/DAC circuits.
• Bus termination for memory modules (e.g., DDR, SDRAM) and communication interfaces.
• Voltage division in precision analog circuits and sensor arrays.
• Industrial control systems where consistent performance under thermal stress is critical.
• Legacy electronics maintenance due to its non-RoHS compliance and robust ceramic construction.

Conclusion of GQCB022490JDT

The GQCB022490JDT stands out for its thin-film precision, compact QSOP form factor, and high power handling in a multi-resistor network. While not suited for automotive or RoHS-mandated designs, its thermal resilience, tight tolerances, and BUS-oriented configuration make it a reliable choice for industrial, telecom, and high-reliability electronics. Engineers will appreciate its balance of performance and durability in space-constrained, thermally challenging applications.
